MARKARFLJÓTSGLJÚFUR IN SHORT

Markarfljótsgljúfur is a deep river canyon in the southern Highlands, about 200 metres deep and around 4 km long, cut by a glacial flood from Katla volcano roughly 2,000 years ago. It is free to visit and only reachable in summer: by 4x4 on the F261 mountain road or on foot from the Laugavegur trail. Allow at least an hour for the viewpoints.

About Markarfljótsgljúfur

The Markarfljót river runs about 100 km from the highlands near Hrafntinnusker down to the sea on the South Coast. In the highlands it has cut a narrow canyon with steep walls of layered volcanic rock, in grey, brown and red tones. At the canyon the river is joined by the Syðri-Emstruá.

The walls are streaked with colour, and where water seeps down them bright green moss grows on the rock, a sharp contrast with the dark sands around. The most accessible stretch of the canyon is about 4 km long, and it is far quieter than the canyons along the Ring Road.

This is remote country. There are no facilities, no shops, and no mobile signal you can count on. It is a place for people who already plan to be in the Fjallabak area or walking the Laugavegur trail between Landmannalaugar and Þórsmörk, not a quick roadside stop. In return you get big views over the canyon and, on a clear day, the ice cap Mýrdalsjökull and the mountains of the interior.

Carved by a volcano flood

Katla is one of Iceland’s most powerful volcanoes and sits under the Mýrdalsjökull glacier. When it erupts under the ice, it melts huge amounts of water very fast. Such floods, called jökulhlaup, have swept down the river valleys of the South many times.

One such flood, about 2,000 years ago, cut Markarfljótsgljúfur. Glacial meltwater still runs through the canyon today, which gives the river its milky grey colour.

How to get to Markarfljótsgljúfur

By 4x4Drivers reach the canyon on the F261 Emstruleið. From Hvolsvöllur, Road 261 runs up through Fljótshlíð and becomes the F261 at the end of the valley, continuing into the highlands past Einhyrningur to Emstrur, where it meets Fjallabaksleið syðri (F210). It is a rough mountain road for proper 4x4 vehicles only, open in summer. It has river crossings, and conditions change with the weather. Ask locally and check road.is before you go.
On foot from LaugavegurHikers on the Laugavegur trail can reach the east-side viewpoint on a short detour between Hvanngil and Botnar, about 10–15 minutes on foot.
On a guided tourHighland tours in super jeeps or 4x4 buses sometimes include the canyon, usually as a stop along the Emstrur route. Check what each tour covers.
By public transportThere is no public transport to the canyon. Highland buses to Þórsmörk and Landmannalaugar run in summer and can be used for a Laugavegur hike, but they do not stop at the canyon itself.

Never cross highland rivers you are not sure about. Water levels rise on warm afternoons and after rain. If you rent a car, check that the rental agreement allows F-roads and river crossings. Most do not for ordinary vehicles.

Best time to hike and what to pack

The paths to the viewpoints are short and easy, but this is the highlands, so dress for more than the walk.

Summer is when locals and visitors hike here. The wind is less cold than at other times of year and the days are long. On a warm, sunny day the temperature in Iceland can reach 20 °C or a little more, but 10–15 °C is more usual, and it is cooler and windier in the highlands. It can rain on any day, so be ready for the temperature to swing.

A basic summer hiking kit: thermal base layers (top and bottom), two shirts, hiking trousers, a waterproof jacket and trousers, sunglasses, sunscreen, a hat and a water bottle. Add sturdy boots, food and a charged phone.

To the west of the canyon is the Tindfjöll range, a cluster of peaks with a small ice cap. From its slopes the view takes in Markarfljótsgljúfur, the Fjallabak highlands, Mýrdalsjökull, Eyjafjallajökull and Þórsmörk.

Best time to visit Markarfljótsgljúfur

Summer (July–August)The only reliable time to visit. Roads open once the snow melts and the mud dries, usually by late June or July. Daylight is long, but the weather can still turn cold and wet.
Winter (October–May)The roads are closed and the area is not accessible without serious winter equipment. Plan to visit in summer.

Safety and practical tips

  • Visit in daylight and keep away from the edge. The canyon walls are steep and can crumble.
  • Bring warm layers, a waterproof jacket and pants, hiking boots, water and food. There is nowhere to buy anything nearby.
  • Tell someone your plan and expected return. Mobile coverage is unreliable.
  • Do not drive off the marked road. Off-road driving damages fragile highland ground and is illegal.
  • Check road.is and vedur.is on the day. Conditions on F-roads change quickly.

Facilities and accessibility

There are no facilities at the canyon. The nearest huts and toilets are along the Laugavegur trail, at Hvanngil and Botnar in Emstrur.
